The BST system uses high efficiency bacterial consortia and a mini-immobilized bioreactor system to purify the toilet wastewater. The special bacterial consortia are self-regenerated in the mini-immobilized bioreactor; thus they can be used for an extended period of time in the BST system without need of replacement.

More importantly, AQUASOL advanced BST system can save large amounts of clean water resources while providing a high quality sanitary treatment system. The biologically purified water, which is completely disinfected with the most powerful germicide - OZONE, can be reused over and over again to safely flush the toilet. Thus, AQUASOL biological self - cleaning toilet system is especially suitable for countries or regions that have serious shortages of water.

According to unofficial statistics, about 8 trillion gallons of clean water is used for flushing toilets per year. Assuming the cost for the water is $ 0.00125 US per gallon, it costs $10 billion US per year. Unfortunately, many cities and regions throughout the world are facing a serious water shortage, saving water for more important uses is becoming a top priority globally.

In addition, the AQUASOL biological self-cleaning toilet (BST) has a compact design that minimizes the space requirements for installation. Low cost and low maintenance are among many advantages the AQUASOL biological self-cleaning toilet (BST) can provide.
